RAIL-BRAKE.

SPECIFICATION forming part of Letters Patent No. 512,140, dated January2, 1894.

Application filed November 9, 1893- Serial No. 490,474. (No model.)

To all rah/011a it may concern:

Be it known that I, EDWIN TENISON WIL- SON, a citizen of the UnitedStates, residing at Ashmore, in the county of Ooles and State ofIllinois, have invented certain new and useful Improvements in RailOar-Brakes; and I do hereby declare the following to be a full, clear,and exact description of the invention, such as will enable othersskilled in the art to which it appertains to make and use the same.

This invention relates to car brakes of that class which act directly onthe rail with lateral pressure against the sides thereof; and

aims to provide a simple mechanism for simultaneously raising andlowering the brake beam and tilting the same upon their fulcrum so as tomove the brake shoes to and'from the sides of the rail.

The improvement consists of the novel features and the peculiarconstruction and combination of the parts which will be hereinafter morefully described and claimed and which are shown in the annexed drawings,in which Figure l is a cross section of a car truck showing theapplication of the invention and the relative position of the same inelevation. Fig. 2 is a detail View of a brake mechanism showing therelative disposition of the parts when the brake shoes are pressedagainst the sides of the rail.

Acar truckAmay be of any approved form of construction and is designedto carry the brake mechanism upon a crossed timber B which is providedat each end with upper and lower guides D and E, respectively. Thevertical brake beams F are provided in pairs and are pivoted betweentheir ends to a cross bar G and carrybrake shoes 6 at their lower endswhich are designed to press laterally against the sides of the rails O.A vertical bar H is adapted to work in the guides D and E and looselythrough the cross bar G and is connected at its upper end with the upperends of the brake beams F by links h. A lever I horizontally disposedand pivoted between its ends to the crossed timberB is operativelyconnected at its outer end with the vertical bar H by a pivotal joint,and is pivotally attached at its inner end to a vertically operating rodJ to which the poweris applied for actuating the brake mechanism. Aspring K is applied to the rod J and operates on the same in such amanner as normally to hold the brake mechanism out of operativeengagement with the rail. The power for actuating the brake mechanismmay be manual or steam and is applied to the said rod J in anyconvenient manner. 7 It will be understood that each side of the truckwill be shut larly equipped and that there will be a lever .I foroperating the brake beam on each side of the truck.

The parts being disposed substantially as shown in Fig.1 the spring Kwill serve to hold the brake shoes free of the rails. Then it is desiredto apply the brake power is applied to the vertical bars J to operatethe levers I and the brake shoes 6 through the intervening connectionsherein set forth. The first result effected is the lowering of the brakeshoes to the plane of the head of the rails C after which, a continuedoperation of the rod J will cause the brake shoes to move laterally andbear against the sides of the rails with sufficient pressureproportionate to the force applied to the rod J to slacken the speed ofthe train, as will be readily understood.

The brake shoes e are beveled at their opposite ends on their innerfaces to prevent" the ends engaging with projecting portions on thesides of the rails, thereby obviating injury to the brake mechanism.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, is-

1. In a rail brake for cars, the combination of vertical brake beamsconnected between their ends by a cross bar a vertical bar H passinglooselythrough the said cross bar G and held from lateral motion in itsvertical movements, and connected at its upper end by pivoted links withthe upper ends of vertical beams and means for moving the said bar Hvertically whereby the brake beams receive a vertical movement and atilting motion on their pivotal connection with the said cross bar G,substantially as set forth.

2. In a rail brake for cars, the combination of vertical brake beamsconnected between their ends to a cross bar, a lever I operativelyconnected at one end with the said brake beams to actuate the samesubstantially in the manner set forth, a Vertical bat-J having links itconnecting the bar H with the brake connection with the opposite end ofthe said beams a lever I, a vertical Mr J connected lever and adapted tohave the power applied with the said lever I and a spring applied tothereto, and a spring applied directly to the the said bar J,substantially as set forth. :5
